I talked to my Dr about it, because i was having terrible migraines. I got told I could have coffee only up to 12 oz a day though. That's it.
I have 1cup of coffee everyday .. Nd the pimple are pregnancy acne my sister had it an as soon as she gave birth to her daughter her face Nd back cleared up.
No coffee isnt bad as long as you dont over do it, idk about the pimple things though. Try googling it?
